How can I use a trademark that the Trademark Clearinghouse validated?

During a registry's sunrise period: register yourtrademark.tld using the unique code, called SMD (Signed Mark Data), which you received after validation of your trademark. For such a code, it is required that you include a proof of use in your trademark registration.

During the registry's claims period: you will be notified if somebody registers yourtrademark.tld.
